FEED-WATER REGULATOR.

GZ ECIFICATION forming part of Letters Patent No. 320,093, dated June 16, 1885.

Application filed April 3. 1885. (No model.)

To all whom it may concern:

Be it known that I, WVILHELM BITTER, engineer, a citizen of Prussia, and a resident of Altona, in the Kingdom of Prussia, have invented a new and useful Improvement in Feed-\Vater Regulators for Steam-Boilers, of which the following is a specification.

This invention relates to feed-water regulators such as are known as Berrymans regulators, the object of which is automatically to regulate the level of water of steam-boilers by starting or stopping a feed-pump or other feeding apparatus, as required. The starting or stopping may be produced by the apparatus in opening or closing a tap-valve, by shifting a driving-belt away from or to a loose pulley, or other mechanical operations for such purpose.

The apparatus consists of a closed vessel that communicates by means of two sets of tubes with the interior of the boiler. The one set of tubes, attached at one end to the upper part of the said vessel, reaches with its other free end down to the normal water-level of the boiler, while the other set of tubes, connected at one end to the bottom of the said vessel, terminates somewhat below this level.

Each set of connecting-tubes between vessel and boiler consists of three parts with piv otal connections so arranged that the vessel can swing on fulcrum on one of the connect-- ing tube-pieces without closing at any time the communication between vessel and boiler.

In the drawings, Figure 1 designates a side view of the apparatus, partly in section, and Fig. 2 a ground plan, partly in section. Fig. 3 shows the apparatus in connection with a steam-boiler.

A is a closed vessel, of spherical or other convenient shape, which communicates by means of the tubes a c c with the normal waterlevel, while by the tubes a, 0, and c the vessel communicates with a part of the boiler below the normal level of water. The tubes 6 and e are attached to hollow sockets B and B, provided on a standard or baseplate, into which sockets tubes 0 are fitted in a pivotal manner and packed steam-tight by stuffingboxes (I and (1, respectively. By a double socketpieee, b, the tubes 0 a and c a are connected in a way so as to allow of a circulation of steam or water through c a and c a, respectively.

f f, g g, and h h are plugs, which can be unscrewed and removed for cleaning the passages of the tubes, it required.

The operation of the apparatus is as follows: If the level of water reaches up to or above the end of tube a, water is by the pressure of steam forced through the tubes 6 c e do a into the vessel A. By the weight of the water the vessel A is caused to descend and to turn the tubes 0 c in the sockets B B. If, on the other hand, the level of water falls below the end of tube 0, steam enters into vessel A through said tube and forces the water out of vessel A back into the boiler. By the action of a counterweight, P, on a lover, .2, connected with the vessel A, the latter is caused to ascend and return into its raised position. These up and down movements of vessel A are employed for opening or closing a stopcock valve, r, of a steampipe for starting or stopping of a feed-pump, or for throwing in and out of operation a feeder of any other kind in any suitable way or man ner.

In what is known as Berrymans regulator there have been used. between the vessel A and the boiler, elastic tubes which allow of a falling and rising of the vessel if filled by or emptied of water. These elastic tubes, however, have not always operated successfully, as they had to be of such very small diameter to secure the required elasticity that they soon filled with sediment or other impurities, by which the communication between the boiler and the vessel A is stopped. The improved arrangement by which the vessel fulerums or turns brackets B 13 allows of the employment of communicating tubes of any caliber, which do not get blocked easily, and which by the application of plugs f, g, and h can be cleaned without trouble at any time.

I am aware that it is not new to employ in connection with a boiler and an elevated waterwsupply reservoir a cock-shell in which is fitted a plug containing water and steam chanr bers, and a water receiver or globe connected with the plug by pipes which communicate with the water and steam chambers therein and balanced by a weighted lever. In this apparatus, when the globe or receiver is in its elevated position, the water-chamber in the plug is in communication with the elevated reservoir, and water flows from said reser- 1 do not desire to include an apparatus of' the kind above described in my invention. In my apparatus the vessel A is always in free communication with the boiler, and said vessel receives its waterfrom the boiler itself, and

after it has fallen by increase of weight the Water is returned therefrom to the boiler. The feed-pipes are entirely independent of. the

pipes whereby the top and: bottom of the vessel A are in uninterrupted communication with L the boiler.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with a steam-boiler and tubes 6 e, entering the boiler at different levels, of the hollow sockets B B, withwhich the tubes 6 e are in constant communication, the tubes 0 c, entering and free to turn in the sockets BB, the vessel A, and tubes at a, extending from the top and bottom thereof, and the coupling-piece 1), connecting the tubes a a and c c and serving to maintain the top of the vessel A in constant communication with the boiler through the tubes a c e, and the bottom of said vessel in constant communication with the boiler through the tubes a c tially as herein described.
